What is a gender pay gap? 

A gender pay gap is defined as “the difference between women’s and men’s average weekly full-time equivalent earnings, expressed as a percentage of men’s earnings [1].” 

The Australian Bureau of Statistics has calculated that, on average, women working full-time earn $239.80 less per week compared to men, a difference of 15.3% [1]. More specific wage gaps have been calculated, including a difference of 14.1% for Australian Stock Exchange executives [2] and a larger gap of 17.7% for workers at non-public organisations [1].   

Importantly, the gender pay gap does not directly compare like roles. The definition is broadly inclusive of the many complex causes that contribute to differences in women and men’s wages. 

What causes the gender pay gap? 

The gender pay gap is a complicated phenomenon. Research has indicated a number of major contributors, including the industries that women and men tend to occupy, the impact of career interruptions, differences in negotiation tactics and outcomes, and opportunities for leadership.

Why is the gender pay gap detrimental?     


Fundamentally, the gender pay gap is an issue of fairness and equity. A society in which half the population earns considerably less due to their gender is not one where people are treated equally. However, there are also individual, organizational, and social reasons to close the gap.  

Importance for women 

The gender pay gap leads to financial disparity between women and men. This is especially the case for retirement savings; women retire with approximately half the superannuation balance of men [15]. This disparity leads to women being vulnerable to financial distress in retirement and in the event of divorce. This has contributed to women over 55 years being the fastest growing group of people experiencing homelessness [16]. Additionally, gender pay gaps lead to women experiencing lower career satisfaction compared to men [17].  

Importance for organisations 

Women who are not satisfied with their work or careers are more likely to leave their current role [18]. Turnover is costly for organizations; knowledge is lost when employees walk out the door. Finding a suitable replacement and training them takes both time and resources. 

Importance for society 

The Australian government provides support for individuals in distress. If women’s retirement savings are considerably lower than men’s, governments are more likely to be called upon to financially support these women. The burden of homelessness in older women is also an additional strain for social services. Additionally, statistical modelling has shown that eliminating Australia’s gender pay gap could be worth $93 billion dollars – or 8.5% of Australia’s GDP [19].  

Strategies for organisations to address the gender pay gap  

Many promising solutions have been proposed for organizations to tackle the wage gap. The Workplace Gender Equality Agency is a great starting point for seeking resources.  

Conduct a pay gap analysis to identify the causes.  

Before an issue can be addressed, it needs to be understood. The Workplace Gender Equality Agency provides a toolkit that organisations can use to conduct an analysis of where pay gaps exist and the underlying causes of this gap [20]. If and when a gap is found, the toolkit provides a guide for taking action to address the gap [21]. 

Stop talking about merit!  

What comes to mind when you think of a manager? It’s likely that you’re thinking about the “ideal worker”: someone who works full-time, has had an uninterrupted career, and is focused on the organisation [22]. This is often the form of merit against which candidates for a managerial role are assessed. As long as we keep using this version of merit – and believing this form of merit leads to a fair process – the gender pay gap will persist [23]. 

Be a leader 


Yes, you! Why not consider becoming a Pay Equity Ambassador (PEA) to promote this worthy cause? Both men and women are encouraged to take part; in fact, there are more male pay equity ambassadors than female ambassadors!  

PEAs help to highlight support pay equity as an issue that is important to individuals, organisations and society as a whole. But they are also part of the solution by helping to communicate ways that individuals and organisations can identify and address any pay inequity.
